最近在做公司一个商城项目，涉及到了微信分享，上网找了几篇博客看了看，总结下做个无脑教程，算是自己的一个总结，不喜勿喷，有错欢迎指出。
所需材料
一份导包：
implementation 'com.tencent.mm.opensdk:wechat-sdk-android-with-mta:+'
五份权限：
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
class文件两个：
微信分享文件.png
appID一个：这个需要在微信开发平台注册自己的app,具体前往这里查看
以上就是所有所需的东西，接下来开始动手把代码打上再调用就可以了
WXEntryActivity.class
这个class是
public class WXEntryActivity extends AppCompatActivity implements IWXAPIEventHandler {
private IWXAPI api;
private WXShare wxShare;
String flag;
String url;
String title;
String content;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.fragment_share_item);//这个布局文件随便放一个透明的就行
flag=getIntent().getStringExtra("flag");//1:分享至朋友圈;0:分享至好友
url=getIntent().getStringExtra("url");
title=getIntent().getStringExtra("title");
content=getIntent().getStringExtra("content");
wxShare = new WXShare(this);
wxShare.setListener(new OnResponseListener() {
@Override
public void onSuccess() {
}
@Override
public void onCancel() {
}
@Override
public void onFail(String message) {
}
});
Log.e("WXEntryActivity", "WXEntryActivity");
WXShare share = new WXShare(this);
api = share.getApi();
wxShare.share(flag,"这是要分享的文字");//分享文本
if (flag.equals("0")){
wxShare.shareUrl(0,this,url,title,content);//分享链接
}else {
wxShare.shareUrl(1, this, url, title, content);
}
//注意：
// 第三方开发者如果使用透明界面来实现WXEntryActivity，
// 需要判断handleIntent的返回值，如果返回值为false，
// 则说明入参不合法未被SDK处理，应finish当前透明界面，避
// 免外部通过传递非法参数的Intent导致停留在透明界面，
// 引起用户的疑惑
try {
if (!api.handleIntent(getIntent(), this)) {
finish();
}
} catch (Exception e) {
e.printStackTrace();
}
}
@Override
protected void onStart() {
super.onStart();
wxShare.register();
}
@Override
protected void onDestroy() {
wxShare.unregister();
super.onDestroy();
}
@Override
protected void onNewIntent(Intent intent) {
super.onNewIntent(intent);
Log.e("onNewIntent", "onNewIntent");
setIntent(intent);
if (!api.handleIntent(intent, this)) {
finish();
}
}
@Override
public void onReq(BaseReq baseReq) {
}
@Override
public void onResp(BaseResp baseResp) {
Intent intent = new Intent(WXShare.ACTION_SHARE_RESPONSE);
intent.putExtra(WXShare.EXTRA_RESULT, new Response(baseResp));
sendBroadcast(intent);
finish();
}
WXshare.class
public class WXShare {
public static final String APP_ID = "这里填你注册成功的微信appid";
public static final String ACTION_SHARE_RESPONSE = "action_wx_share_response";
public static final String EXTRA_RESULT = "result";
private final Context context;
private final IWXAPI api;
private OnResponseListener listener;
private ResponseReceiver receiver;
public WXShare(Context context) {

this.context = context;
}
public WXShare register() {
// 微信分享
api.registerApp(APP_ID);
receiver = new ResponseReceiver();
IntentFilter filter = new IntentFilter(ACTION_SHARE_RESPONSE);
context.registerReceiver(receiver, filter);
return this;
}
public void unregister() {
try {
api.unregisterApp();
context.unregisterReceiver(receiver);
} catch (Exception e) {
e.printStackTrace();
}
}
//分享文本
public WXShare share(int flag,String text) {
WXTextObject textObj = new WXTextObject();
textObj.text = text;
WXMediaMessage msg = new WXMediaMessage();
msg.mediaObject = textObj;
// msg.title = "Will be ignored";
msg.description = text;
SendMessageToWX.Req req = new SendMessageToWX.Req();
req.transaction = buildTransaction("text");
req.message = msg;
req.scene= flag == 0 ? SendMessageToWX.Req.WXSceneSession : SendMessageToWX.Req.WXSceneTimeline;
boolean result = api.sendReq(req);
Log.e("text shared: " + result, "");
return this;
}
//flag用来判断是分享到微信好友还是分享到微信朋友圈，
//0代表分享到微信好友，1代表分享到朋友圈
//分享链接
public WXShare shareUrl(int flag, Context context, String url, String title, String descroption) {
//初始化一个WXWebpageObject填写url
WXWebpageObject webpageObject = new WXWebpageObject();
webpageObject.webpageUrl = url;
//用WXWebpageObject对象初始化一个WXMediaMessage，天下标题，描述
WXMediaMessage msg = new WXMediaMessage(webpageObject);
msg.title = title;
msg.description = descroption;
//这块需要注意，图片的像素千万不要太大，不然的话会调不起来微信分享，
//我在做的时候和我们这的UIMM说随便给我一张图，她给了我一张1024*1024的图片
//当时也不知道什么原因，后来在我的机智之下换了一张像素小一点的图片好了！
Bitmap thumb = BitmapFactory.decodeResource(context.getResources(), R.mipmap.logo);
msg.setThumbImage(thumb);
SendMessageToWX.Req req = new SendMessageToWX.Req();
req.transaction = String.valueOf(System.currentTimeMillis());
req.message = msg;
req.scene = flag == 0 ? SendMessageToWX.Req.WXSceneSession : SendMessageToWX.Req.WXSceneTimeline;
api.sendReq(req);
return this;
}
public IWXAPI getApi() {
return api;
}
public void setListener(OnResponseListener listener) {
this.listener = listener;
}
private String buildTransaction(final String type) {
return (type == null) ? String.valueOf(System.currentTimeMillis()) : type + System.currentTimeMillis();
}
private class ResponseReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
Response response = intent.getParcelableExtra(EXTRA_RESULT);
Log.e("type: " + response.getType(),"type: " + response.getType());
Log.e("errCode: " + response.errCode,"errCode: " + response.errCode);
String result;
if (listener != null) {
if (response.errCode == BaseResp.ErrCode.ERR_OK) {
listener.onSuccess();
} else if (response.errCode == BaseResp.ErrCode.ERR_USER_CANCEL) {
listener.onCancel();
} else {
switch (response.errCode) {
case BaseResp.ErrCode.ERR_AUTH_DENIED:
result = "发送被拒绝";
break;
case BaseResp.ErrCode.ERR_UNSUPPORT:
result = "不支持错误";
break;
default:
result = "发送返回";
break;
}
listener.onFail(result);
}
}
}
}
}
调用
Intent intent = new Intent(getActivity(), WXEntryActivity.class);
intent.putExtra("flag", "1");
intent.putExtra("title","链接的标题");
intent.putExtra("content", "链接的介绍");
intent.putExtra("url", "你要分享的链接");
startActivity(intent);
其实就是一个简单的Activity跳转加传值
成果
